Polarity correspondence effect between loudness and lateralized response set.

Chang S, Cho YS - Front Psychol (2015)

Bottom Line: Performance is better when a high pitch tone is associated with an up or right response and a low pitch tone with a down or left response compared to the opposite pairs, which is called the spatial-musical association of response codes effect.In Experiments 1 and 2, in which participants performed a loudness-judgment task and a timbre-judgment task respectively, the correspondence effect was obtained between loudness and response side regardless of whether loudness was relevant to the task or not.The results suggest that loudness produced polarity codes that influenced response selection (Experiments 1 and 2), and additional spatial codes provided by stimulus position modulated the effect, generating the stimulus eccentricity effect (Experiments 3 and 4), which is consistent with the polarity correspondence principle.

ABSTRACT
Performance is better when a high pitch tone is associated with an up or right response and a low pitch tone with a down or left response compared to the opposite pairs, which is called the spatial-musical association of response codes effect. The current study examined whether polarity codes are formed in terms of the variation in loudness. In Experiments 1 and 2, in which participants performed a loudness-judgment task and a timbre-judgment task respectively, the correspondence effect was obtained between loudness and response side regardless of whether loudness was relevant to the task or not. In Experiments 3 and 4, in which the identical loudness- and timbre-judgment tasks were conducted while the auditory stimulus was presented only to the left or right ear, the correspondence effect was modulated by the ear to which the stimulus was presented, even though the effect was marginally significant in Experiment 4. The results suggest that loudness produced polarity codes that influenced response selection (Experiments 1 and 2), and additional spatial codes provided by stimulus position modulated the effect, generating the stimulus eccentricity effect (Experiments 3 and 4), which is consistent with the polarity correspondence principle.

Mentions: Analyses of variance revealed the main effect of loudness, F(1,14) = 12.36, p = 0.0034, MSE = 204, = 0.56. Faster RTs were obtained with high-level loudness tones (M = 411 ms) than low-level loudness tones (M = 420 ms). The interaction between stimulation position and response side was significant, F(1,14) = 71.00, p < 0.0001, MSE = 535, = 0.95, reflecting the auditory Simon effect. When the stimulation position and response side were matched, the mean RTs were shorter (M = 398 ms) than the non-matching mapping (M = 432 ms). The interaction between loudness and stimulation position was also significant, F(1,14) = 7.86, p = 0.0141, MSE = 58, = 0.19. When the sound was presented to the right ear, high-level loudness tones (M = 411 ms) elicited faster responses than low-level loudness tones (M = 416 ms). When the sound was presented to the left ear, high-level loudness tones (M = 411 ms) elicited faster responses than low-level loudness tones (M = 423 ms). Even though the 3-way interaction of loudness, response side and stimulation position was only marginally significant, F(1,15) = 3.11, p = 0.0996, MSE = 138, = 0.18, the tendency was similar to the results from Experiment 3; when the sound was presented to the right ear, the correspondence effect was greater (8 ms) than when the sound was given to the left ear (0 ms; see Figure 6). Any effects regarding timbre-to-response mapping did not reach significance, indicating that it is not a critical factor for the correspondence effect between loudness and response side.

ABSTRACT
Performance is better when a high pitch tone is associated with an up or right response and a low pitch tone with a down or left response compared to the opposite pairs, which is called the spatial-musical association of response codes effect. The current study examined whether polarity codes are formed in terms of the variation in loudness. In Experiments 1 and 2, in which participants performed a loudness-judgment task and a timbre-judgment task respectively, the correspondence effect was obtained between loudness and response side regardless of whether loudness was relevant to the task or not. In Experiments 3 and 4, in which the identical loudness- and timbre-judgment tasks were conducted while the auditory stimulus was presented only to the left or right ear, the correspondence effect was modulated by the ear to which the stimulus was presented, even though the effect was marginally significant in Experiment 4. The results suggest that loudness produced polarity codes that influenced response selection (Experiments 1 and 2), and additional spatial codes provided by stimulus position modulated the effect, generating the stimulus eccentricity effect (Experiments 3 and 4), which is consistent with the polarity correspondence principle.
